We see these reactions in some groups of organisms that have evolved under different environmental conditions and in our own bodies during times when oxygen is not readily available. UNITY AND DIVERSITY: Other reactions (such as fermentation) can produce biologically usable energy, but they are usually less efficient.Usable cellular energy is released in the form of ATP.Collectively the reactions are called cellular respiration.

The rearrangementsВ occur in a series of steps rather than all at once.(C 6H 12O 6В +В O 2)В haveВ higher energy than (CO 2В + H 2O) so this rearrangement releases energy.

Living things rearrange food (specifically glucose - C 6H 12O п»ї 6п»ї ) and O 2В into CO 2В and H 2O.Living things get energy by rearranging food and oxygen molecules.Food has energy in the form of calories.When the reactants have more potential energy than the products, energy is released in the reaction (вЂњdownhillвЂќ reaction).Energy is transformed in chemical reactions. Energy is conserved, neither created nor destroyed.Food consumed in excess of what we need for energy and growth/repair is converted to fat and stored.Some of our digested food is broken down and rearranged to build new macromolecules we use to repair tissue and to build new body tissue.New Ideas from Biosynthesis (this triangle) The products are expelled from the body as carbon dioxide and water. It is rearranged to obtain energy in a reaction called cellular respiration. Some of this matter is really taken in for energy.Ideas from Cellular Respiration (previous unit) Some of this matter (especially much of the water but also some indigestible material) basically passes through us.Some of this matter is used in our body, but we take in much more matter than we need to use to grow or maintain body structures.We also take in matter as oxygen and water. Food has matter in the form of protein, carbs and fats- the same things we find our bodies are made of.Matter is rearranged in chemical reactions. Matter is conserved, neither created nor destroyed.Ideas from Chemical Reactions (previous unit) For more information, see the MBER Essential: Close Enough.

Note that the wording of each statement should reflect those of your students. Be sure to track them publicly with your students as you move through the learning segments. These models have been building since Chemical Reactions and so represent a fairly lengthy list of ideas. In our work with cellular respiration, we primarily add ideas to a model for Energy from Food. It provides an engaging, relevant, and rigorous program of instruction for any NGSS-aligned states integrating Earth Science with Biology.As we move through the remainder of the Red Model SequenceВ and develop ideas about matter and energyВ in organisms, we explicitly develop two models in parallel. The Living Earth offers a learning experience anchored in student-relevant phenomena and problems. Crosscutting Concepts, Disciplinary Core Ideas, and Science and Engineering Practices are fully integrated in all activities and assessments. The introduction to each chapter provides a checklist of student learning aims matched to specific activities for easy navigation. Environmental literacy is well supported through checkpoints and questions, and design challenges are addressed in context as appropriate. Students are encouraged, through the activities, to collaborate with their peers and be open to modifying their models and explanations based on evidence. Practical investigations are clearly identified and easily accessible no special kits are required. The analysis and interpretation of data and text, independent research and inquiry, and use of conceptual and physical models underpin the design of the activities. The chapters build progressively on knowledge and skills and there is an interconnectedness throughout the book as students explore and explain phenomena. The book is organized into six instructional segments, with an additional reference chapter supporting mathematical and computational skills. This phenomenon-based title is fully three-dimensional in its approach, employing the 5Es instructional model to encourage inquiry and build a deeper understanding of science as a discipline. The Living Earth has been designed and written to meet the requirements of the California Science Framework (HS Three-Course Model). SKU: EL-TLE2 Categories: Course Books eBooks Product Description
